WebFeb 10, 2024 · The interrupting-current rating (also known as short-circuit rating) of a fuse or circuit breaker is the maximum current it can safely interrupt. If a fault current exceeds a level beyond the interrupting capacity of the protective device, the device may actually rupture, causing additional damage. WebThe breaking capacity of a circuit breaker was rated in MVA earlier considering the rated breaking current and rated operation voltage of a CB. It can be calculated as follow: Breaking Capacity = √3 x V x I x 10-6 …. MVA. or. Interrupting or Breaking Capacity = √3 x Rated Line Voltage x Rated Line Current x 10-6 …. MVA.
